SRAM
PG-1070 Cassette (10-Speed) $99.00

Item # SRM0526

Description

Silent and smooth.

With the introduction of the Force and Rival road groups, SRAM brought some long-overdue, fresh-thinking to component design. Thankfully, SRAM's creativity and innovation didn't stop at components with show-stopper aesthetics like shift levers and cranksets. Instead, it's evenly extended to parts that're traditionally thought to be rather mundane, like the cassette. And unlike other cassette manufacturers, who maintain multiple models of cassettes despite the minimal differences between them, SRAM did the sensible thing: It offers a highly scaled back range of cassettes. The standard model, found here, is known as the PG-1070 Cassette, while the deluxe model is known as the OG-1090.

Whether you're riding a Red, Force, or a Rival-equipped bike, the 'PowerGlide' shifting of the PG-1070 cassette will provide crisp, positive shifting under any circumstance -- whether it be a mellow spin, or at max power on a steep climb. And, unlike either Dura-Ace and Record, the PG-1070 weighs in at a scant 220 grams without having to resort to easily-worn titanium cogs. Rather, the PG-1070 is made from durable heat-treated steel, giving you tons of mileage before you'll need to replace it.

The PG-1070 is available in several ratios. Its spline configuration allows it to fit on any Shimano 9- or 10-speed freehub, and it's compatible with any 10-speed chain: SRAM, Shimano, or Wippermann's S-series chains. What SRAM suggests, of course, is that you use one of its 10-speed PC-1000 series chains for optimal shifting. And, in addition to the aforementioned, the PG-107 includes a forged, anodized, and laser-etched lockring.

The actual weight of the SRAM PG-1070 Cassette varies with tooth count, but for reference, the 11-25t is around 224 grams.

I had the og-1090 (11-25). It was loud. I switched to this and i got to go up to a 12-28. I notice no difference in weight/watts required or shifting performance. If anything this one seems better cause it is newer.

Likewise, I am currently running a Wipperman & it works fine. I don't think it's any quieter...I don't think its lasting any longer than the SRAM (but I ride old-school, with no electronics or measurements xcept my wrist watch, so I don't have any mileage to report). But it shifts as good as SRAM despite the warning on the chainring that states "only use SRAM chains".

The PG1070 system is great! I run the 11-26 and live in mountainous area where climbing is common. Love this system and SRAM makes great cassettes. You can't go wrong with the quality............your only decision is what gear range you want!

Sram's 70 lineup has been a staple in my stable of bikes. Between cassettes and chains, I find it to the best trio of performance, weight, and their friend money. The cassette has a noticeable weight drop from it's thrifty brother, the 50 lineup, with more peepholes and an aluminum carrier cradling the larger sprockets. Durability is dependable for many miles and the ability to pull the cassette apart allows deep cleaning after miles of neglect.
